Closes #77

[SkyHyve]

removed network checks for tunnel_network and tunnel_network6 as they should be allowed to specify non-network addresses to have static client ip addresses. This is in line with how the pfsense GUI works and even in line with the examples provided by the pfsense GUI.

I added checks for IPv4/IPv6 address before I saw this PR #85

I'm pretty sure we don't want to remove all checks. pfSense uses the following validation check:

function openvpn_validate_tunnel_network($value, $ipproto) {
        $value = trim($value);
        if (!empty($value)) {
                if (is_alias($value) && (alias_get_type($value) == 'network')) {
                        $net = alias_to_subnets_recursive($value);
                        if ((!is_subnetv4($net[0]) && ($ipproto == 'ipv4')) ||
                            (!is_subnetv6($net[0]) && ($ipproto == 'ipv6')) ||
                            (count($net) > 1)) {
                                return false;
                        }
                        return true;
                } else {
                        if ((!is_subnetv4($value) && ($ipproto == 'ipv4')) ||
                            (!is_subnetv6($value) && ($ipproto == 'ipv6'))) {
                                return false;
                        }
                }
        }
        return true;
}

I'm going to close this and look closer at #85. Thanks for the PR though.
